EFFECTS OF EXPLORATION AND COACHING INSTRUCTIONAL STRATEGIES ON ELECTRICAL INSTALLATION AND MAINTENANCE WORK STUDENTS’ LEARNING OUTCOME IN TECHNICAL COLLEGES IN BAUCHISTATE

Abstract

The study investigated the Effects of Exploration and Coaching instructional strategies on learning outcomes of Electrical Installation and Maintenance Work Students in Technical Colleges in Bauchi State. Four research questions and four null hypotheses guided the study.Relevant literature was reviewed in line with the objectives of the study. The study adopted a quasi-experimental research design of pretest, posttestnon-equivalent control design. The population of the study comprised 263 National Technical College Year Two (NTC II) students offering Electrical Installation and Maintenance Workin eight Technical Colleges in Bauchi State for the 2020/2021 session.Purposive and simple random sampling techniques were used to sample four technical colleges having male and female students with a sample of 134 students and a simple random sampling was used to assign the fourTechnical Colleges into experimental groups I and II for the study. The instrument used for data collection was the Electrical Installation and Maintenance Work Achievement Test (EIMWAT) and Electrical Installation and Maintenance Work Interest Inventory (EIMWII). EIMWAT and EIMWII were validated by three (3) research experts. To ascertain the internal consistencies of the instruments, Kuder Richardson 21 (KR 21) was used forEIMWAT and a coefficient of 0.76 was obtained,on the other hand, the Cronbach Alpha reliability technique was used forthe EIMWII instrument and a coefficient of 0.78 was obtained. The data for research questions were analyzed using meanwhile the hypotheses were tested using Analysis of Covariance (ANCOVA) at p < 0.05 level of significance. The findings of the study revealed that exploration and coachinginstructional strategies significantly increased academic achievement and interest of learning of the students but the group taught with coaching instructional strategy had the highest mean achievements score (15.3 > 15.2) and the highest mean interest score (22.1 > 20.2) than group taught with exploration instructional strategy. The result of the hypotheses tested at 0.05 level of significance,with a p-value of 0.518 on electrical installation and maintenance work achievement mean score showed that there was no significant difference in the achievement mean score, but with a p-value of 0.003 on electrical installation and maintenance work interest mean score shows that there was a significant mean difference in the interest of learning as regards the instructional strategies. Also, the gender of the students significantly influences their achievement and interest but male students had high achievement and interest mean scores than female students. There is no significant interaction effect of the treatment given to the students and their gender concerning achievement and interest in electrical installation and maintenance work. Based on the findings, of the study, therefore, it is recommended among others that more attention should be given to the inclusion of modern instructional strategies such as exploration and coachingfor teaching Electrical Installation and Maintenance Work and other Technical and Vocational Trades in Technical Colleges in Nigeria.
